Three star charts on exoplanets

In these three celestial star charts grouped all available information about exoplanets currently available. Each of them should be extended to enlarge:

1. This letter highlights the sky where the stars have been detected potentially habitable exoplanet. Each is represented by corresponding brightness.

2. Sky this letter represents the 600 stars which together contain about 800 exoplanets now known. Naturally the letter provides an overview of the distribution of the same and not necessarily details of each of these solar systems.

3. On this chart are represented exoplanets not visible by direct methods, as well as above methods require precise location.
